Can nucleolus be found in prokaryotes
WebSep 7, 2024 · The eukaryotic cells types are generally found in animals, plants, algae, and fungi. For the purpose of this article, the primary focus will be the structure and histology of the animal cell. The major differences between animal and plant cells will be explored as well. As previously stated, the fundamental components of a cell are its organelles. WebIn eukaryotes, ribosomes form in the nucleolus, a structure inside the cell’s nucleus. As ribosomal proteins enter the nucleus, they join with four rRNA strands to create a complete ribosome. The subunits exit the nucleus through pores and begin protein synthesis in the cytoplasm of the cell. In prokaryotes, proteins combine with three rRNA ...
